This question is similar to my other question however this has to do with Logos.
If I am in public (on public property) and take a photo that has a recognizable company logo in it what rights do I have to reuse the photo with the logo in it? (Commercially via the web.) I know this answer could depend on the way the logo is used. If the logo is used in a positive light how does that change if used in a negative light?
One example would be this:
I have a photo of two trucks both with logos of ice cream companies. In front of the trucks is an ambulance (with its lights on). The placement of the trucks with the ambulance is amusing as it indicates eating ice cream can get you a visit from an ambulance. I would use the photo in a amusing way though I know if looked at wrong it can be taken in a negative way.
Notes: I am based in Colorado, USA but will accept answers that can apply worldwide. Also I know a lawyer could provide a definitive answer, however, I am looking for a general idea.
